Lead-acid and lithium batteries are both made in BCI Groups GC2/GC2H (6 Volt) and GC12 (12 Volt) sizes, but what about BCI Group GC8/GC8H (8 Volt) batteries? Are there 8 Volt lithium golf cart batteries?
Here is our attempt to answer this question and to clarify few things about not only lithium golf cart batteries, but about lithium batteries in general.
Golf carts and other electric vehicles rely on their built-in batteries to provide them with enough power and energy for propulsion.
In order to increase the range and acceleration of the golf cart, the golf cart battery must be able to both store and to be able to release plenty of energy, often rapidly, while not causing weight penalties. Also, the golf cart battery must be able to cycle a lot, tolerate deep cycle discharges, to accept the charge quickly and similar. These requirements are not easy ones...
Regular generators and inverter generators are very similar devices that convert the chemical energy of the fossil fuel into mechanical energy (rotation of the internal combustion engine and electric generator) and mechanical energy into electric energy.
However, although their operation is very similar, internally there are several, very important differences...
48V lithium golf cart batteries offer many benefits including some serious weight savings, more efficient battery chemistry, a larger number of charging/discharging cycles, faster charging, longer range, etc.
However, the price of 48V lithium golf cart batteries is higher than the price of the 48V lead-acid golf cart battery pack - at least in the beginning. In the long run, 48V lithium batteries save both money and time ...
The car battery provides energy not only for cranking the engine, but it also powers a broad range of devices that may be turned on when the engine is off, even when the car is locked, like GPS units, alarms, and other security systems, multimedia devices, lights, etc.
While car batteries feature a nominal voltage of 12 volts, in real life, this voltage can be anywhere from just a few volts (or even 0 volts!) to almost or even slightly over 15 volts. The exact battery voltage depends on the engine being turned On or Off and the battery's charge condition, age, load, temperature, etc.
Electric golf carts are powered by onboard battery packs which must be replaced from time to time. Commonly, electric golf carts use 36 volts and 48 volts electric systems, although 72 volts electric golf carts are becoming more and more popular.
Electric golf cart battery packs are based on 6V, 8V, and 12V lead-acid batteries, although in recent times, 12V, 24V, 36V, and 48V golf cart lithium batteries are also being manufactured. So, how many batteries are in a 48-volt golf cart?
Conversion between Cold Cranking Amps (CCA) and Amp Hours (Ah) is not a direct one, for one very simple reason: Cold Cranking Amps describe the ability of the battery to provide strong currents required for starting/cranking of internal combustion engines, usually for 30 seconds, while Amp Hours (Ah) describes the capacity of the battery and its ability to provide certain current for, usually, 20 hours.
Basically, Cold Cranking Amps (CCA) and Amp Hours (Ah) both describe the capacity of the battery and its ability to provide current for some time - they are just two extremes of the battery usage.
Lawn mower, tractor, and garden starting batteries are used for starting/cranking internal combustion engines and sometimes for powering other electric loads, including lights, smaller winches, various pumps, and similar devices.
When looking for a new battery, one must pay attention to several details in order to get the right battery that will serve well for years ahead.
Dual fuel power generators are types of generators that can out-of-box use both gasoline or propane, which can be very helpful in emergencies where gasoline can be hard to find.
Also, propane as fuel has many advantages over gasoline - it is more environment friendly, it stocks up more easily, it is more engine-friendly fuel, etc.
Wet/flooded, gel-cell, AGM, and lithium 12V 100Ah deep cycle batteries are a very popular group of deep cycle and dual-purpose batteries, offering relatively large capacities (100+ Ah), a large amount of stored energy (1200+ Wh), and large discharge currents at acceptable price and weight.
Due to the maintenance requirements, wet/flooded batteries are used rarely, with the SLA Gel and AGM batteries being most common. Also, lithium 12V 100Ah batteries are getting more and more present on the market, offering huge weight savings.
Trolling motors are commonly used as means of propulsion on kayaks of various sizes, especially on fishing kayaks, intended for longer fishing trips that last for hours and sometimes even for days.
The main issue any kayak owner has is the kayak's load capacity. While electric trolling motors are lightweight and feature excellent weight to thrust ratio, their batteries are anything but light - unless lithium kayak trolling batteries are used.
Fish finder batteries for kayaks and smaller boats must be lightweight and compact, but accept charge quickly from various sources, and should be able to power the fish finder during the entire fishing session without the need to be recharged before going to shore or starting the main engine (if present).
Fish finder batteries are spill-proof AGM and Gel-Cell lead-acid batteries and Lithium Iron Phosphate (LiFePO4) batteries. Most fish finder batteries feature nominal capacity in the 5 - 20 Ah range.

Power inverters for cars and trucks are becoming increasingly popular due to the large number of devices and gadgets that must be powered or at least occasionally charged while in the car.
As such, car power inverters should feature a car cigarette lighter adapter plug (12V DC) providing high-speed charging for smartphones, tablets, cameras, drones, but also for laptops and similar devices. However, due to the power limitations of the car cigarette lighter adapter, the output power of car inverters is also limited.
Space heaters are commonly used for heating tents, RVs, offices, rooms, cars, and even homes and apartments. They directly convert chemical or electrical energy into heat, warming up the desired area. Since space heaters directly convert chemical energy into heat, they are simple, reliable, and rather affordable, but also they are not as efficient as, for example, Air Conditioning units.
Battery operated heaters can be of great help when camping or being off-the-grid by keeping You warm during long, cold days and nights. Right? Well, things are not that simple ...
Watts to BTU and BTU to Watts conversions are commonly required when calculating the power of devices that are used for air heating and cooling, like various AC units and electric heaters.
'Slight' issue is the fact that BTU is a unit of energy, while watts are a unit of power, and they can't directly be converted.
While HP is a unit of power, kWh is a unit of energy and direct conversion of these two units is not possible, without introducing the third parameter - time (T[s]).
kWh to HP and HP to kWh conversions are very important when both power and energy of internal combustion engines are transferred, stored, and compared with the energy and power of electric motors, inverters, pumps, winches, and other similar units that are powered by electric energy.
Power generators are used when electric power is needed and mains power is not present - when camping, tailgating, in emergencies, and similar.
One of the very important features of power generators is - noise level. A loud power generator can be very annoying, especially when working for a longer period of time. On the other hand, a quiet power generator is a robust and reliable, but almost silent unit, giving peace of mind in more ways than just one ...
Lead-acid and lithium 100 Amp-Hour batteries are commonly used in automotive, marine, industrial, and off-the-grid applications as starting, dual-purpose and very often, as deep-cycle batteries.
Since they commonly used in many critical systems (medical, security, etc.) many people wonder how long can a 100Ah battery last under a certain load.
Regardless of the car battery type or brand, from time to time it may become necessary to recharge the car battery using the battery charger. Was the battery discharged due to the parasite load, multimedia devices, or for some other reason, is not the topic of this article.
However, if that happens several times over a short period of time, check the alternator and the rest of the electric system of your car.
Here is a simple volts and amps to watts calculator, with short explanations, formulas, and charts.
